Features of the biology of Scutellaria baicalensis Georgi (Lamiaceae) from different ecologo-geographical places of growth during introduction

Keywords: climate, seasonal development, introduction


An analysis of the variability in the development of Scutellaria baicalensis Georgi (Lamiaceae) plants collected from natural habitats (Zabaikalsky Krai, Amur Region, Primorye) and grown under the same culture conditions (Novosibirsk) is given. It has been established that in S. baicalensis, under new growing conditions, interpopulation differences in morphological characteristics and the timing of the onset of phenophases developed in nature are preserved. Data analysis shows the existence of significant differences ( t > 3) between the steppe Zabaykalsky and forest Primorsky cenopolations (CP) in plant height, number of pairs of leaves, number of shoots both in nature and during introduction. The flowering period in the Zabaykalsky CP comes earlier, compared to the Primorsky CP, both in nature and in culture. In Zabaykalsky CP in culture, individuals bloom in early July. In the Primorsky CP, the flowering period begins at the end of July-August, the seed ripening period is extended, especially in the first years of introduction. The formation of steppe Zabaykalsky and forest Primorsky ecotypes can be assumed.
